Lettore Optiarc Imac 20'' mooolto schizzinoso

[BdT]

Ciao
pur avendo letto qua e là che la qualità dei lettori inseriti negli Imac non è il massimo, vorrei provare gli ultimi tentativi prima di.....boh? comprarne uno esterno?
In pratica al caricamento dei cd (originali) fa un casino impressionante che poi si placa..ultimamente sembra di sentire una motosega al lavoro con un po' di sordina e il/i cd non me li legge per niente. non proprio tutti: solo quelli che ho appena acquistato originali.
ho provato rese di pram e smc pur non sapendo a cosa potessero servire e dato un comando da terminale che mi dà un lungo resoconto di cui non ci capisco una mazza.
qualcuno può darci un'occhiata? così, giusto per capire se ci sono altri rimedi o mettermi l'anima in pace ed eventualmente consigliarmi l'acquisto di uno esterno....

graaazieee!

[Simone.m]

Da quel poco che vedo sembra definitivamente morto, troppi errori in log e poi il comportamento hardware che fa ogni lettore cd che non legge.

Per caso la velocità dei cd schizza al massimo e senti un "clik clik" molto rapido che continua finchè il tutto non si placa?

[BdT]

nei casi migliori... quello che ho postato è decisamente il peggiore

morto..??? sigh
